Product details
Overview
DPC817L-C-TR from Diodes Incorporated is a high-reliability phototransistor-based optocoupler in SLM-4 package, providing galvanic isolation with 5000 VRMS isolation voltage, CTR of 200–400% at IF = 5 mA / VCE = 5 V, and guaranteed operation from −55 °C to +110 °C - used for feedback control in isolated DC-DC converters and I/O signal conditioning in industrial PLCs.
For engineers reviewing the DPC817L-C-TR datasheet, DPC817L-C-TR pinout, DPC817L-C-TR application, or DPC817L-C-TR equivalent, key selection criteria include CTR rank C (200–400%), VCEO = 35 V, VCE(SAT) ≤ 0.2 V, isolation compliance (UL1577, VDE EN IEC 60747-5-5), and SLM-4 surface-mount compatibility for high-density board layouts.
Technical Context
The DPC817L-C-TR integrates an AlGaAs infrared LED coupled to a silicon NPN phototransistor in a single-molded SLM-4 package. Its current transfer ratio is specified over full temperature range (−55 °C to +110 °C), with CTR min 200% ensuring robust switching margin under aging and thermal stress.
It supports DC and low-frequency AC signal isolation up to 80 kHz bandwidth (−3 dB), with rise/fall times ≤18 µs into 100 Ω load. The device meets safety standards UL1577 (5000 VRMS, 1 min), CQC GB 4943.1-2022, and VDE EN IEC 60747-5-5, enabling use in reinforced insulation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP185(GB-TP,F) | CTR 130–260%, VCEO = 35 V, SO-4 package (3.5 mm × 4.6 mm), higher CTR tolerance spread. | SO-4 footprint requires PCB redesign; lower max CTR reduces margin in precision feedback loops. | Select when space-constrained layout favors SOIC and CTR >130% suffices for target loop gain. |
| PC817X3NIP0X | CTR 200–400%, DIP-4 through-hole package, same electrical specs but 4.6 mm height vs. SLM-4's 3.5 mm. | Not suitable for fully SMT production; incompatible with automated pick-and-place for low-profile assemblies. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with TLP185(GB-TP,F) and PC817X3NIP0X, DPC817L-C-TR delivers identical CTR rank and isolation rating in a lower-profile, reflow-optimized SLM-4 package - making it preferred for high-volume, space-sensitive industrial and automotive modules requiring zero post-reflow handling.

FAQ
What is the maximum forward current rating for DPC817L-C-TR?
The absolute maximum forward current (IF) is 60 mA, but the recommended operating condition is ≤50 mA for long-term reliability. At IF = 5 mA, the device achieves its rated CTR of 200–400%; exceeding 20 mA increases LED degradation risk without meaningful CTR improvement.
Does DPC817L-C-TR support AC signal coupling?
No - it is a DC-coupled phototransistor optocoupler optimized for static or low-frequency switching (≤80 kHz). It lacks base connection for linear AC modulation; for analog signal isolation, Diodes' ILD217T or similar linear optocouplers are required.
Is the SLM-4 package compatible with standard 0.1-inch DIP footprints?
No - SLM-4 has 2.54 mm (0.1 inch) lead pitch but differs mechanically from DIP-4: it is surface-mount with gull-wing leads, 11.5 mm length, and 3.5 mm height. It requires dedicated SMT land patterns per Diodes' recommended pad layout (C = 2.54 mm, C1 = 10.86 mm).
What safety certifications does DPC817L-C-TR hold?
DPC817L-C-TR is certified to UL1577 (5000 VRMS, 1 min), CQC GB 4943.1-2022, and VDE EN IEC 60747-5-5. These approvals validate its suitability for reinforced insulation in end-equipment complying with IEC 62368-1, IEC 61000-4-5, and IEC 60601-1.
